Song of the South. As I kid I loved Brer Rabbit the cartoon portions of the film are great. Disney won't even release it on DVD because of the live action sequences. It's a pity they could re-edit it.

All of the Carry On movies.

Some of the Tom and Jerry cartoons are banned pick your reason as to why? Colour, offensive to large people, cruelty to animals, violence in children's programmes etc. They'll be going after Scooby Doo next.

Dumbo (because of the crows) hang on they are remaking that so let's see how that scene plays.

Birth of Nation this is in the AFI most important films list it was made just after the WW1. The Klan are the heroes of the movie I kid you not, unbelievably racist.
